Merge branch '3.3'

Conflicts:
	Kwc/Form/Component.php
remove unused empty method
don't remove and re-add resource, as that drops all rules

instead add setParentResource method that allows changing the parent
don't check for Component and ComponentClass interface

isAllowedComponentById also checks the class
use same signature as Zend_Cache to avoid strict errors
use twolevel cache for assets
support cleaning apc cache backend from cli

also remove Apc Itertor when clearing cache, that doesn't work reliable
improve session validators

- empty session before regeneration
- use own validators that don't just throw an excption, instead empty the session
ensureHttps also when using Session_Namespace
